Lower Claiborne Aquifer: Alabama, Arkansas, Louisiana, Mississippi 2006-2008

Digital hydrogeologic surface of the Lower Claiborne aquifer in Alabama, Arkansas, Louisiana, and Mississippi. The hydrogeologic unit dataset contains 414 rows and 394 columns representing 1-mile grid spacing. In general, limitations of data interpolation included areas of sparse geophysical log control points, log datums not clearly defined for some logs, unknown exact extent of each hydrogeologic unit in subcrop, interpolation limitations, and values averaged over 1-mile grid spacing.美国阿拉巴马州、阿肯色州、路易斯安那州及密西西比州境内下克莱本含水层（Lower Claiborne aquifer）的数字水文地质界面数据集。该水文地质单元数据集包含414行与394列，数据以1英里的网格间距表征。总体而言，数据插值存在多方面局限：包括地球物理测井控制点分布稀疏的区域、部分测井的测井基准面界定不清晰、隐伏露头区域内各水文地质单元的确切展布范围未知、插值方法自身存在局限，以及基于1英里网格间距取平均得到的数值所带来的精度限制。
